You play by adding tiles to the chain. Tap a tile in your hand, and if one of its numbers matches an open end of the line, it's placed there. If you can't play, you draw from the boneyard.

The line grows from both ends:

• Matching an end means placing a tile whose number matches one of the two open ends of the chain. A six can be added to an end showing six, extending the line.
• Drawing from the boneyard is what you do when no tile in your hand matches either open end. You draw until you can play, or pass if the boneyard is empty.

You win a hand by playing all your tiles first. If nobody can move, the game is blocked and the lowest total of pips left in hand wins.

Points accumulate across hands. The computer sharpens across eight levels, tracking numbers more shrewdly as you climb.

Tips

• Track which numbers are running out. Each number appears on a limited set of tiles, so noticing that most of the sixes are already played tells you a six-end is hard for anyone to answer.
• Watch what your opponent can't play. When the computer draws or passes, it reveals a number it can't match, so steering the open ends to that number can keep it stuck and drawing.
• Play your heavy tiles early. If a hand ends blocked, the pips left in your hand count against you, so shedding high-value tiles early reduces your risk of a costly total.
• Keep both ends in mind. You can add to either end of the chain, so think about how a move changes both open numbers, not just the one you're matching.
• Hold a double when it's useful. A double tile can be tricky to place, but holding one of a common number can also give you flexibility, so weigh whether to play it early or keep it as an answer.
• Don't reveal your weakness. Just as you read your opponent, they read you, so try not to make it obvious which numbers you're desperate to see on the open ends.
